"Connection Timed Out" issue

Hi, I have a little problem... I cannot connect to my own server.

Non stop when I am trying to join to my server, it's keep showing
one message "Connection Timed Out".

I don't know what do i need to do to solve this error. I've tried to

use DynIP, I've tried to flush DNS and change DNS, I've waiting

if it'll repair itself, but it is fourth day when i cannot join to it.

I'll appreciate that if someone would help me with that error. :>

(and sorry for my grammar but i'm come from Poland so...)

Try connecting to your server with the secondary IP (the bottom one here when the server is online

I've alread tried and nothing happend.

When I am trying to connect to my server, it's just showing that:

I don't know what can i do else.

According to your server log you're trying to connect to the server while it is not even fully started.

Additionally it looks like it's running out of RAM, try to remove some plugins

Still i cannot join, i've removed some of my plugins and nothing happens.

It's still the same problem.

It could also be related to too many worlds.

Disabling autoload or deleting some will probably help

I've deleted 5-6 worlds and still nothing ._.

Quote from Roman

Did you also delete them from the multiverse configuration files?

Nope.

Quote from Roman

Then you should do that, otherwise multiverse will recreate all worlds on the next start

OK, now i need just launch server and i changed my server from Spigot to PaperMC, because one of moderators give me this solution.

Now i have other problem, when I am trying to join to my server, my server is simply turning off

First line means "fix your "world" using Minecraft Region Fixer or MCEdit,

second means "delete "world"

and third means "Delete issue-maker chunk from the world using MCEdit or deleting region file".

What can i do without deleting my main world?

Okay, I solved the problem. I just needed to turn on "force world upgrade" and it solved the problem, but anyways thanks for help :>
